Sisteme Radio Fikse; Pajisje pikë-pikë; Hierarkia Dixhitale Pleziokrone (PDH); Sistemet radio dixhitale STM-0 me kapacitet të ulët dhe të mesëm që punojnë në bandat e frekuencave në diapazonin nga 3 GHz në 11 GHz

Fixed Radio Systems; Point-to-point equipment; Plesiochronous Digital Hierarchy (PDH); Low and medium capacity and STM-0 digital radio system operating in the frequency bands in the range 3 GHz to 11 GHz

Scope

The present document specifies the minimum performance parameters for low and medium capacity terrestrial fixed service digital radiocommunications equipment operating in the frequency bands between around 3 GHz and 11 GHz but nevertheless such systems should provide the efficient use of the spectrum under any conditions. The present document covers equipment intended to be used at nominal data rates for PDH systems between 2 Mbit/s and 2 × 34 Mbit/s and for SDH systems transmitting STM-0 signals with a VC3 payload capacity. Consideration has to be given to special requirements of the local and access network especially different network structures with high density nodes.
